Notes:
The Raman spectra of KClO3 are reported at room temperature up to pressures of 60 kbar in a diamond-anvil cell. The phase transition between phases I and II occurs at approximately 7 kbar, is sluggish and the spectra show that the two phases coexist over a pressure range of approximately 5 kbar. The Raman spectra of phases I and II differ appreciably in the Cl—O stretching region and the spectra of KClO3 II can be interpreted in terms of the predicted unimolecular rhombohedral cell which has no inversion centre. Mode Grüneisen parameters have been calculated for most of the modes observed and are used in an attempt to assign some of the lattice vibrations.
